The invention relates to a vehicle model identification technology, in particular to a hybrid neural network vehicle model identification method based on audio feature fusion. According to the invention, the problem of low recognition accuracy when a traditional vehicle model recognition technology is applied to complex illumination and weather environments is solved. The invention discloses the hybrid neural network vehicle model identification method based on audio feature fusion. The method is implemented by adopting the following steps: step 1, randomly destroying audio signals of a to-be-trained vehicle model: randomly selecting 80% of vehicle audio signals from the destroyed vehicle audio signals, and then superposing environmental noise on the selected vehicle audio signals; step2,constructing the hybrid neural network; step3, inputting the fusion features with the labels into the hybrid neural network for supervised training; and step 4, inputting the vehicle audio signal of the vehicle model to be identified into the trained hybrid neural network. The method of the invention is suitable for vehicle model identification.
